Also you can download kmperformancing3.7z - and get updated version of the old ScribeFire along with new Scribefire Next.
I need some help from experienced XULers as I can't get Settings tab of tis one working.
P.S.What doesn't work in new ScribeFire Next are:
1) export/import Scribefire options
2) page context menu item 'Blog this' which inserts current page link into your post

I think these are non-critical deficiencies, but I'll be glad to get some help on getting them back to life in KM.
